Li Bai belongs to romanticism and Du Fu belongs to critical realism. Li Bai's poems often use imagination, exaggeration, metaphor, personification and other techniques to produce magical brilliance, magnificent and moving artistic conception, unrestrained, fresh and elegant, rich in imagination, wonderful in artistic conception, wonderful in language, romantic and clear in artistic conception.
The style of Du Fu's poems is basically "gloomy and frustrated", and the language and text structure are full of changes, emphasizing the refinement of words and sentences. Narrative poetry is good at spreading out, summarizing highly, depicting details in detail, and expressing feelings in detail. Lyric poetry is a realistic poem, which integrates scene, lyric, discussion and narrative, euphemistically and tactfully, ups and downs.
2. Different ideas.
Many of Li Bai's poems show the idea of seeking immortality, revealing that life is like a dream, eating and drinking to escape from reality, which is also the representative of upright and arrogant literati in feudal society. Most of Du Fu's poems and works reflect the social outlook at that time, with a wide range of themes and far-reaching significance, especially describing the sufferings of the people and expressing his sympathy for the people and his feelings of worrying about the country and the people. So Li Bai is called "Poet Fairy" and Du Fu is called "Poet Saint".
3, the background and theme are different.
Li Bai lived in the prosperous Tang Dynasty. He has a heroic personality, loves the mountains and rivers of the motherland and has traveled all over the country. He wrote many magnificent poems praising famous mountains and rivers. At the same time, during the prosperous Tang Dynasty, the national strength was strong, and most scholars were eager to make contributions. Li Bai regarded himself as an unparalleled talent and compared himself with Dapeng, Tianma and Xiong Jian, showing his indomitable character.
Du Fu lived in the late Tang Dynasty, and experienced the Anshi rebellion, war and displacement, and the process from prosperity to decline in the Tang Dynasty. He hated evil, exposed and criticized the corruption of the imperial court and the dark phenomenon in social life. He sympathized with the people and was even willing to make sacrifices to save their suffering. Therefore, his poetry creation always runs through the main line of worrying about the country and the people.
